摘要
在线监测并分析SF6气体的状态参数的变化对于SF6电力设备故障的发现、诊断、定位有很大的帮助。笔者根据变电站通信网络和系统的最新国际标准IEC 61850协议,设计了变电站SF6气体智能监测装置,它属于智能电子设备(intelligence electronic device,IED)中的一种专用装置。文中给出了具体的软硬件设计,完成了符合智能变电站标准的IED的建模和相关配置过程,实现了对SF6断路器的监测和信息共享功能的一体化。运行结果表明,该装置可准确监测断路器SF6气体的温度、密度和压力等信息,并可通过IEC 61850协议将数据传输至在线监测数据中心。
SF6 gas is widely used in electric power equipment, and it＇s state parameter reflects SF6 power equipment running status, on-line detection and analysis of the state of the parameters SF6 gas changes for the discovery of equipment failure, diagnosis and positioning has very great help.Based on the substation communication network and system the latest international standards IEC 61850, SF6 Intelligence Electronic Device（IED）is designed, the design of hardware and software is given out in details, the modeling and the configuration of IED accord with smart substation standard are complished, and the monitoring,protection and information sharing are realized as a whole by this IED. The running results show that the density, pressure and temperature are monitored precisely, and the above data can be transferred to the monitoring centre by IEC 61850.
